I have a 2017 MacBook Air with an Intel i5 processor. I have a 1st generation S4. I have tried EVERYHTING I can to get the MacBook to recognize the controller, or visa versa. New USB cable, legacy drivers, new drivers…. The controller is not showing up in the Audio Setup section of the preferences, so I can't select. Tried a couple of maps and nothing. What else can I do?
